A note about the word slave used in this man page and command name: starting with Redict version 5, if not for backward compatibility, the Redict project no longer uses the word slave. Please use the new command REPLICAOF. The command SLAVEOF will continue to work for backward compatibility.
The SLAVEOF command can change the replication settings of a replica on the fly.
If a Redict server is already acting as replica, the command SLAVEOF NO ONE will
turn off the replication, turning the Redict server into a MASTER.
In the proper form SLAVEOF hostname port will make the server a replica of
another server listening at the specified hostname and port.
If a server is already a replica of some master, SLAVEOF hostname port will stop
the replication against the old server and start the synchronization against the
new one, discarding the old dataset.
The form SLAVEOF NO ONE will stop replication, turning the server into a
MASTER, but will not discard the replication.
So, if the old master stops working, it is possible to turn the replica into a
master and set the application to use this new master in read/write.
Later when the other Redict server is fixed, it can be reconfigured to work as a
replica.
